Bihar aur Jharkhand ke climate ke hisaab se cement grade, steel grade aur brick quality kaise select karein.
Cement — Grade Aur Use
OPC 43 grade general RCC work ke liye theek hai, jabki OPC 53 grade high-strength structural work — columns aur beams — ke liye behtar hai. PPC cement plaster aur brickwork ke liye acha rehta hai kyunki iska setting time zyada hota hai.
Hamesha manufacturing date check karein. 3 mahine se purana cement apni strength kaafi kho deta hai.
Steel — Fe500 Ya Fe550
Residential construction ke liye Fe500D grade TMT bar sabse balanced choice hai — strength aur ductility dono achi milti hai. Earthquake zone mein ductility (D grade) important hai, aur Bihar ka bada hissa seismic zone IV mein aata hai.
Hamesha ISI-marked branded steel lein aur rusted bars use na karein.
Bricks Aur Alternatives
Achi quality ki red clay brick ka water absorption 15% se kam hona chahiye aur awaz tez honi chahiye jab do bricks takraayein. AAC blocks halke hote hain, isliye structure par load kam padta hai aur insulation behtar hota hai — garmi mein kamre thande rehte hain.
Bihar aur Jharkhand ki garmi ko dekhte hue AAC blocks ya cavity wall ek accha long-term investment hai.
